2 P1Describe the potential prompts that initiate the installation of new or upgraded softwareProblems with the existing system.Unstable software that leads to system crashSoftware no longer supported by manufacturer – so no user support & updates for it.Security issues with the current software – leading to malicious attacks.Current software incompatible with the new operating system.Additional functionality required: such as strong parental control that was lacking in Windows XP and that is now available in Windows Vista or 7.Another example upgrading your antivirus program to a full internet security suite that will include firewall and anti spyware.

3 New hardware requiring new or upgraded softwareNew hardware requiring new or upgraded software. What is the software called to install when you attach a new hardware.To fix bugs- that will reduce the system to crash or hang.Company Policy: a company may have a policy that only certain software can only be installed. When new installations and upgrades will be carried out

4 Lets brainstorm and check the internet for some answers: M1 Explain the advantages and disadvantages of installing and upgrading softwareLets brainstorm and check the internet for some answers:Look at the prompts to get further ideas:Think about cost, any restrictions, security, stability, training, usability, performance

5 D1 – Justify to the managers why installing their anti virus software would be advisableJust because there is a prompt for change, it doesn’t mean that an organisation will agree to the change going ahead.Installing & upgrading software is often expensivecost of the softwareAdditional cost such as training, ‘down-time’ needed to install the software.Therefore it is important to have a good business case showing that the benefits outweighs the costs of the new software or upgrade.Benefits such as – greater efficiency, improved systems security.Use the factors you have learnt from other units on how viruses and worms can affect the operations of a business to support your answer.

6 P2 – Describe the potential risks of installing or upgrading software‘Down-time’ – when the current system will be inactive while installingIncompatibility issues : imagine what would happen to your existing files when you switch from Windows to Linux

7 How would the above factors affect the business operations?D2 – Evaluate the potential risks of installing and upgrading software and explain how the risks could be minimisedDown-time – careful planning would be required. Think about the best time to install. What kind of resources would be stopped when you install a system on a server for example?Incompatibility issues: switching OS, upgrading Ms word 2003 – 2007 files could not be opened.How would the above factors affect the business operations?

8 D2 – How risks can be minimised?BackupsInstalling at low risk timesIncremental installation: you can install on a few Pc’s, evaluate and test for any problems, then gradually installing the rest – benefits, the business can still run their operations.
